My favourite gadget

I choose two favourites gadgets because if I don't have one of them the other doesn't work. Is a pencil and a paper. I got it more than 10 years ago. I use it for everything, to make presents, to do list, for classes, and the most important to write my thoughts and feelings. I use it everyday, every moment, I prefered over the cell phone or the notebook.

I like because with this gagdgets I can do everything, I don't getting boring, and is useful.

My life would be awful, because is my "guarida". Always is there, when I angry, happy, sad, anxious or "lost".

Is the best gadget in the world! Pencil and paper calm down me.
